What we checked before selling it, and what we measured ourselves.
Why cats scratch the sofa, and what to do
A cat does not scratch to destroy: it marks, maintains its claws and stretches. Forbidding the sofa corner without offering better simply moves the problem to the armchair.
A place in the sun: setting a cat up at the window
A cat watches from a high point, and a window sill is almost always too narrow to lie on. The cleanliness of the glass when you fit it decides far more than the stated weight rating.
A corner of its own: why a cat hides
Hiding is not fear: a cat under cover sleeps more deeply because it no longer watches its back. And the size of the shelter matters far more than its apparent comfort.
